"The aim movable axially of the bolt and compresses isal 38 when the hanger swings "or moves latefaliy toward the arm; After some wear in the "eber'iing '26-, as sh'ewn, the arm when ni'oved lateral-1y by tne hanger can t 'on an axis transversely 6f the 'bolt and compresses bothunit's br pads 36 and 38. It will be "understand that late'i al swingg "6 the hanger will generally ee'cn'r' after some even between the hanger and the pin, as shown in the hushed opening 52 in the head 10 and initially such movement is accommodated by manufacturing tolerances which do not provide for a tight fit of the pin in opening 52. The control arm also resists pivotal or rotational movement of the hanger in its normal plane about the bolt by stressing the resilient units in shear. This action is helpful in releasing the brakes, as will be readily understood by those skilled in the art.

In brake equipment of the type under consideration, the hangers at opposite sides of the truck are interconnected by beams (not shown) and the arms associated with respective hangers control the movement thereof laterally in different directions whereby their movement in both directions laterally is restrained.

Referring now to the second embodiment of the invention as illustrated in Figures 3 and 4, the structure is similar to the previous embodiment and like parts are identified by identical reference numerals. In the present modification the lower end of the control arm or lever 28 is enlarged laterally to provide a seating portion or abutment H30 adjacent one side of the shank 5 of the hanger and a nonmetallic material I02, such as brake lining, is secured to the seating portion Hill in an convenient manner, as by rivets I06, the lining being engageable with the hanger upon movement of the hanger laterally toward the arm. The upper end of the arm, as in the previous embodiment, is sleeved onto the enlarged portion 24 of the pin 28 and is urged against the outer side of the lug M by a resilient unit H38, identical with units 36 and 38, and compressed between the head 48 of the bolt asat H0 and the control arm or lever as at- H2. The portion 24 as in the previous embodiment preing spaced depending lugs, a hanger having an end interposed between the lugs, pivot means extending through said lugs and said end of the hanger affording a ivotal connection between the hanger and support, abutment means at opposite ends of said pivot means disposed adjacent the remote sides of said lugs and in engagement therewith, one of said abutment means being of cylindrical form and engagin the adjacent lug along a surface extending transversely of said pivot means, a head on said abutment means spaced from the adjacent lug, a control arm pivoted at one end on said one abutment means and in frictional engagement at one side with said surface, a resilient bushing sleeved onto said one vents overcompression of the resilient unit as r it is initiallycompressed by tightening the nut 22, the portion 24 abutting lug I l.

Figure 5 illustrates the thirdembodiment of the invention and comprises a hanger 208 with a bifurcated upper portion forming spaced legs '202 and 2M arranged in side-by-side relationship and spaced laterally with respect to each other. The leg 202, which is part of the hanger proper, is received between spaced lugs 206 and 208 of a bracket 2H) which may be part of the truck frame. The leg 262 is pivotedon a pin or bolt 2l2 which extends through aligned openings in the spaced lugs 206 and 208 and opening 2| 4 in'leg 202. The pin comprises a nut assembly 2% atone end and a cylindrical head 2!!) at its opposite end which engage the remote sides of the lugs 206 and 208, respectively. The other leg, arm or lever portion 204 of the hanger comprises an opening 220 through which extends a cylindrical head 2l8 of the pin for pivoting the control arm 284. The hanger and the control arm are thus afforded a pivot at spaced points on a common axis on the pin 212. The play between the hanger and the pin is reduced and the hanger is afforded a novel two-point support. Lateral swinging of the hanger is reduced by abutment of portions 202 and 204 with the pin.

It will be understood that in all three embodiments, the lateral swinging of the hanger is controlled by an arm or lever, which in certain embodiments is flexibly connected to the pin and support. All of the embodiments are easy to assemble and disassemble, are effective to control or reduce lateral swinging of the hangers, and

are useable with existing brake equipment since no changes in the support brackets is required.

abutment means between said head and the other side of said arm and in engagement therewith and compressed therebetween axially of said pivot means, and nonmetallic lining material on the other end of said arm engaging said hanger at an area intermediate the ends thereof.

2. In a brake arrangement, a support, a nut and bolt assembly extending through said support, abutment means at opposite ends of said assembly tightly engaging oppositely facing surfaces of the support, a control arm pivoted at one end on one of said abutment means, a hanger pivoted at one end on said assembly between said surfaces, resilient means mounted on said abutment meansand compressed axially of said assembly against said arm, and nonmetallic lining carried by the other end of said arm in engagement with the hanger, saidhanger being movable longitudinally of the control arm whereby loading of the hanger will not load the arm.

3. In a brake arrangement, a support comprising spaced lugs, a pivot element extending through said lugs, abutment means atopposite ends of said element tightly engaging the remote sides of said lugs, a' hanger pendulously suspended at one end from said element between said lugs, a head integral with one of said abutment means and spaced axially of said element outwardly of the adjacent lug, a control arm pendulousl suspended at one end on said one abutment means between said head and the adjacent lug, resilient means mounted on said one abutment means and compressed against said arm axially of the element, said resilient means including a rubber bushing between the head and arm and in engagement therewith, and a nonmetallic lining on the other end of said arm engaging said hanger in an area intermediate the ends thereof.

4. In a brake arrangement, a support comprising spaced lugs, pivot means extending through said lugs and having abutment means tightly engaging the remote sides of said lugs, a hanger pendulously suspended at one end from said pivot means between said lugs, a control member pendulously suspended at one end from one of said abutment means, resilient means mounted on said one abutment means and compressed against said arm to restrain movements thereof, and nonmetallic lining on the other end of said arm extending a substantial distance forwardly and rearwardly of said hanger in an area intermediate the ends thereof for flat face abutment therewith, said hanger being rotatable in a plane parallel to said face without actuating said arm, said hanger in moving angularly to said plane against said face being eifective to actuate said arm and stress said resilient means.

5. In a brake arrangement, a support, a pivot element having spaced abutments, spaced lugs on said support connected to said element between said abutments and disposed one adjacent each abutment in engagement therewith, a hanger pendulously suspended from said element between said lugs, a control arm at one side of the hanger pendulously suspended at one end from one of said abutment means, resilient means mounted on said last-mentioned abutment means and formed and arranged to be stressed by said arm during movements thereof, a jaw at the other end of said arm extending around said one side of the hanger and the opposite sides of the hanger adjacent thereto, and a nonmetallic lining within the jaw engaging said sides of the hanger.
